`Speciication forming part of Letters Patent No. l M8429, dated October2li, 1854.

To all whom 'it may concern:

Be it know that I, ABSALOMIREARLE, of

Franklimin the county of Delaware and State of New York, haveinventedccrtain new and useful Improvements in Machines for'Sowing(raiii, of which the following is a full, clear,

'sente a section of the same at theline a: .fr of Fig. 1. Fig. 3represents a longitudinal section of the hopper and its slide detachedfrom the machine. Fig. Ltrepresents a view-f the hopper turned bottomside uppermost. i. Fig.' 5 represents aview'iu 'perspectiveof the twoparts separated, which compose the recipro- Fig. 6 represents a'view ot'the' back ot'one 'of the drill-tubes; and Fig. 7 represents a section atthe line w :v offFig. l, but showing the machine with the seed-tubesremoved and adjusted. for sowing seed broadcast.

' Themachinerepresented-in the vaccompany ing drawings is supported ontwo wheels, A and B, that' turn on the opposteends ot` an axle, C. v.Beneath the openings eof the hopparts are pnt together the tongues gwill tinto the openingsf lot'the lower part, F', and

the tongues g' into the opgningsfof the upper part, F, in such a. manneras to form'per# lows the two parts to be adjustedby'sliiiing themlengthwise iu oppositey directions to Vinintheslide for the receptionofthe seed are brought undei -tle 'openings ve and over the .plates m,and are iilled with the seed,an d when the slide. is pushed 'ontagaiiithe perforatious n are 'moved otf the plates m and the seed dropsdown. The se motions of the slide are eleted by'a series of pins, s,inserted in the' hub ofv tlewlieel-A, which by the revolving' Thisconstruction ally vguard l make h o claim.

of the latter turn a bell-crank, H, as they pass, which is secured by apivot, h, to tire under side of the hopper. One arm of thef'crank is`attached to the slide, and the other'is,iu ka position to be struck byone of the pins?, so that eachhpinas it passes will turn the rm and move'the slide outward'to discharge the seed.

vAs soon as each pin has passed the arm of the bell-crank the slide isinstantlydrawn back by a spring, I. By changingthe' number of the pinsthe vibrations ofthe slide arej'increased or diminished, to sow fasteror slower. The .pins a are adapted to being inserted into andl removedfrom the hub at will. In the joint'ot 'each opening e-that is, betweenthe bottoml of. the hopperand the upperpart otfthe slide-f. 4 'a smallplate,- u, is arranged,the end of which projects into the opening.Behind each plate is a spring, J, which constautlytends to press theplate into theopening e, as represented in Figs. 1 and 3. Thisspring-plate u forms 'ai yielding point, which, as the'slide'ismovedsuddenly back, prevents ther seed resting on it from being canghtin thejoint and bruisedor broken." The drag-bar K of each drill-tube isattached to the front beam ot' the frame D by hinge-joints. Euchdrill-tube L has au opening made in its front and rearsides, through onthe drill-tulle forth'at purpose.

I am'awarethat drill-tubes `have been con-- nected to'dragbars by meansof lugs,.brack ets, braces, and screw-bolts, and that drilltubes havebeen inserted into a beam attached.` to and paralleLwith the axle of,the machine;g but as it is the object of my invention tofdin: pensewithand supersede these de\ices,`Ido not claim thein either separatelybr in connection.

' I am also aware that a spring guard-platehas been adapted to a seriesof rotating disi-` 'charging-cups, but not in such manner `sto detainlany excess of'seed which thefcupauigltt contain and drop it into thenext," Tofsuch a What I claim as myinvention, and desire to secure byLgttcrs'latenisl1'.
